Now, how can it be applied to do useful functions ? Bomb disposal ? Rescue
in a contaminated area ? War function somehow ? Like the drones we have up
in air ?

I posted the following a few minutes ago to a vertebrate paleontology list
that I participate in, and I thought that the list might enjoy the video
that I mention in the posting as well.

==========================================

In a burst of youthful enthusiasm 32 years ago, when I founded AICS
Research, the "AICS" stood for "Artificially Intelligent Cybernetic
Systems." We long ago tired of explaining what that phrase meant so we
condensed the name to simply AICS. Over time, we moved away from robotics
and became primarily a software supplier to Hewlett-Packard and their
customers, but the original intention was to design and build self-learning,
biologically-inspired autonomous mechanisms.

With that introduction, let me show you this video and simultaneously
express my admiration for what the people at Boston Dynamics have been able
to accomplish. This 3 minute video clip was released just a few days ago:

The clip is of "BigDog." It is at once eminently reminiscent of naturally
evolved locomotion and at the same time enormously unsettling in its
alienness.

BigDog has a gasoline engine to power the hydraulic system acuators that act
as its musculature. Proprioception is accomplished by angle and pressure
sensors located at every joint and foot pad, and the CNS is encephalized in
a central CPU, which also processes visual and equilibrium inputs as well.

The end result is quite impressive.

Like most work of this kind, it is funded by the US military, in this case,
the Defense Advanced Research Projects Agency (DARPA), but DARPA is lot more
willing to fund flights of fancy than any of the civilian research granting
agencies and at much higher dollar amounts, and a lot of good work does
eventually come out their efforts. The internet was one of their funded
projects.

EXTREMELY COOL!!!

May I humbly recommend a book that will explain the evolution in this
demonstration? "Out of Control" by Kevin Kelly[1]. Mr. Kelly founded Wired
magazine (Wirt recently informed me that he is also a family member of the
Absolut Vodka empire.) The book actually has a chapter of man's efforts to
build a machine that can walk. One of the first attempts was a "god" attempt
developed by Carnegie-Mellon called Ambler. It was a big machine with six
legs. It would take about a day to walk across the courtyard. Why so slow? Its
brain, which was so big it had to remain on the ground separate from the rest
of the beast, spent most of its time determining the topology and calculating
the next best step. The brain looked at all inputs and every possible outcome
and tried to control EVERYTHING in a "god"-like manner.

Meanwhile, an MIT professor and Australian named Rodney Brooks wrote a book
called "Fast, Cheap and Out of Control". The idea was to create a machine that
can walk by decentralizing the intelligence. Instead of making a really big
brain, he made legs that reacted to certain events. He created a six-legged
machine and programmed each leg separately. When one leg goes up, others know
to push back. The one that's up knows to move down, etc. With the right
sensors and feedback, he built a very stupid machine that walked like a big
roach. The simple rules were so good that if you pulled off a single leg, it
would rebalance itself and continue to walk - much like we saw the big dog do
on the ice in the YouTube clip but he did this in 1990.

The point of the book is that simple well-tuned systems can combine to form
more complex systems. After eighteen years the rules that made the six-legged
"roach" walk became good enough to make a four-legged "big dog" walk. How much
longer will it take to figure out the rules to make a bipedal walking machine?
All without a brain? If you consider how little we think about each and every
muscle while we walk it's eerily similar.

The book contains many more examples of self-ordering systems. IMHO, if I were
like God, this is exactly how I would create the world.
